The washing and fulling of fabrics is usually "carried out nowadays by sewing some pieces of fabric together at their ends and passing them as an endless band,'inost- 5 ly in the form of a rope, between the rollers of the Washing and fulling machine in the direction of the warp threads. During this treatmentfthe warp threads are ,more or less stretched by the action of the own. weight of the fabric'rope and the pressure ofthe rollers, while practically no strain is exertedon the weft threads. In consequence thereof thefabric does not shrink at all or only little in the direction of the warp or length of the fabric but often lengthens even, while it shrinks in the direction of the weft or width of the fabric by about per cent. ceding the washing. and fulling, especially 20 during the weaving itself, the warp threads have already been under a considerable strain too, while the weft threads are always more or less relaxed. These .difi'er- "ences in the tension of the fabric threads- 5 are not only not compensated for, by .the I known washing and fulling methodsbut j forniand good fit in'wearing.

The invention has for its obgect to provide a methodof washing and fulling fabr cs by which the above said disadvantage is avoid- 40 ed, this'object being attained by passing the fabrics through between the washing and fulling' rollers in the direction of. the weft. Theinventionmay be carried into effect by forming-the usual endless band or rope from a number of pieces of fabric of any dQSlIBd 7 Now, during the treatments pre-' the two syslength are sewn to :one another at T 7 their selvedges ,so that. the weft threads willextend in the longitudinal andthe warp threads in'the transverse direction of the band or rope. Duringthe passage of such arope between the washin andfulling rollers the weft threads. are held under strain and the shrinking of the same is more or less prevented. "In'this 'lway the inequality of relaxation of thejtwo systems of. threads 1 otherwise entailed in the washing and fullv ing is avoided. Fabrics thus treated have a better finish." They are weatherproof and the garments made thereof retain' their good form and are resistive against wear. V The accompanying drawing shows a dia grammatic plan view of a portion of afabe ricband or rope made in accordance with the invention. I v 1 g e e The band or rope to be passed through the washing and fulling-machine is formed from a number of fabric pieces a which may have the usual length orshorter lengths obta'iriedby. dividing apiece of the "ordinary:

length into shorter:pieces. The fabric pieces a are sewn toon'e another at the selvedgesff orflists. Z) are the warp threads whichextend in the transverse" directionand 0 the V weft-threads which extend in the longitudi- "nal directionzof the band. The band or rope 7.5

is passed through between the rollers. of the washing and fulling machine in the. direction of'the arrow w,'i. e.- in the direction of the weft threads of the 1 fabric. The

washing] and fulling machines may be of well-known. construction. I v

Havingithus described my invention, what I claim asnew and desire to secure by LettersiPa'tent, is i lies as a finishing operation in their manufacture which consists'in passing the fab-' rics'between the washingand fulling rollersin the direction ofthe weft of the fabric. .2; The method of washing and fulling 9'0 1.

In testimony whereof I'ha've signed my name to this specification.
